What you’ll need

  • A neutral, high smoke-point oil
  • Paper towel or a clean cloth
  • An oven that reaches 220°C
  • The pan itself, washed and dry

Steps

  1. Step 1

    Wash and dry it thoroughly

    Warm water and a stiff brush is fine. A little soap won't ruin a seasoned pan. Dry it completely, including the handle and underside.

  2. Step 2

    Rub a thin layer of oil over the whole pan

    Inside, outside and the handle. Use grapeseed or flaxseed. Skip olive oil here; it burns at a lower temperature and turns gummy.

  3. Step 3

    Wipe off the excess

    The step most people skip, and the one that matters most. The pan should look almost dry; too much oil is what makes it sticky.

  4. Step 4

    Bake it upside down for an hour

    220°C, pan upside down, with a tray underneath to catch drips. Upside down keeps oil from pooling in the base.

  5. Step 5

    Let it cool in the oven

    Turn the oven off and leave the pan inside until it's cool enough to handle. It should come out with a faint sheen and an even, darker colour.

Common mistakes

  • Too much oil

    A thick coat doesn't season faster. It just goes sticky. Wipe until it looks almost bare.

  • The wrong oil

    Olive oil and butter burn at low temperatures and leave a gummy residue instead of a hard finish.

  • Expecting it done in one round

    Seasoning builds over several rounds and regular cooking. The first bake is a start.
